摘要：
Recently, tile-based viewport adaptation is a popular method for 360 video streaming. Our demonstration adopts a rate-mixed transmission approach utilizing a VR adaptation agent at the server end for viewport-based streaming, which is client-compatible and can be scalable to different users. The FOV prediction is applied to improve the viewing experience. The feasibility of our system to head-mounted displays is verified, which can reduce bandwidth consumption by up to 36%.
